Filters

In response to some comments on filters and their usage on CW.
Most if not all Japaneese radios use upper sideband for cw. A properly
operating tranceiver will have a receiver offset of about 800hz. If you
prefer using a lower pitch try offsetting your RIT slightly to compensate.
Note: There are still quite a few DRAKE C-Lines out there with their offset
on lower sideband. Fortunately they can--- zero beat your frequency...
There really is not a good excuse to call CQ in a 250 hz bandwidth.
500hz is much better with 800-1000 being the best choice. Save the 250 for
search and pounce.

Unfortunately, the last several years the ARRL has defaulted the hours
operated to "24" if they could not determine the number of hours from the
summary sheet. This is too bad because it makes it impossible to
evaluate scores/op time. It is difficult for them too because the
contest logging programs often do not include the amount of op time on
the summary sheet.

I will again be doing the write-up for Sweepstakes. Your comments,
stories and impressions of the contest are welcome. Especially those
regarding close battles with local competition, or those with interesting
personal stories.
Please send them directly to me. Will use as many as I can.

NF6H Sweepstakes CW
241Q/71 = 34,222
Low Power (TS930S & HF6V Vertical), ~10 hours operating time
I was mostly trying to work as many multipliers as possible since I've
never gotten a sweep from home. Probably more than a third of the
stations I worked came back to NF6S. If you worked NF6S (who lives
up north) in the ORG section, it was me.
Speaking of top ten lists, how about the top ten most often botched calls?
1. NV6O <> N4BO
2. NF6H <> NF6S
.
.
.
Even I'll admit to botching NV6O more than once. :)
Not worked, never heard: ME, SC, PQ, SK
Not worked, but heard: MAR, YU
I don't know how I managed to work NL7VJ, he was 309 and I'm sure I wasnt
much better there. Heard the VE8RCS pileup, but couldnt hear VE8RCS.
I didnt think too many people would have problems with PAC... seemed like
N6VI/KH6 was on 21.063 ALL DAY Sunday. I sure am happy I started tuning
around up high. I tried CQing a few times with very little success, at
least I wasnt the only one.
I'd *REALLY* like to put up a beam, but my backyard is too small and close
to power lines. If anybody has had decent success with a roof tower and
beam, please let me know. The peak of my roof is about 17', and
I've seen roof towers anywhere from 7' - 17'. Would a 3 element beam
at say 30' perform substantially better than my roof mounted HF6V?
Unfortunately I've never been able to experiment with antennas since I've
always lived in places with antenna restrictions until recently.
Please send any responses directly to me.

That's one thing the SprINT has been good for, you got a lot of
chances at learning those calls...
I just know that W5EHM is W5ESM in plenty of logs. I sent it
right - that's what memory keyers are for, I even put a little
extra space on each side of the H - but so many people would
come right back to ESM. I'd correct them and sometimes get a
"tu" but only about half of them would send the call again
properly.
I'm sure glad I don't have an H in my own call or a K at the end...

K4XU sez ... "due to a math error, I ended up operating 15 minutes over ...
now trying to figure which QSO's to cut! ..."
answer: "the last fifteen minutes, 0245Z -to- 0300Z, of course"
otherwise ... we must all operate the full thirty hours, then log-off our
poorest six hours. I've heard of others using this interpretation ... is
it "allowed"???
How about an SS SPRINT category???? Some suggestions have been ... six
hours, ten hours (like NAQSOP), any twelve, best twelve, first twelve, last
twelve .... a SS SPRINT category would surely be a HIT!
Someday, (I hope) the SS will be shortened. Forty years ago it covered
two weekends, like the Novice Roundup. Then it was shortened to 48 hours,
and finally, around 1960 it was shortened (amid mucho oppistion) to the
peculiar present day 30 hour format. (Old-timer's please help out here).
The last major SS rule change would have been around 1977 when we dropped
the 1.5 QSO point multiplier for "A" power QSOs????? (remember that????)
Back then one of the toughest sections for a clean sweep was KZ5 in the
Panama Canal Zone!....
and SS super stations were W9IOP and W4KFC.
I dunno, its been sooooo long since a SS rule change ... it seems like we
may be stuck with the 30 hour format forever.... But add a Sprint
category, and see what happens ... (could work for the ARRL DX tests too)

I had a conversation with a friend who is a noted audiologist, and he says
that this is a well understood fact in that profession. Due to the way the
Cochlea (inner ear) processes sounds, we are more acute in distinguishing
pitch for the lower frequencies. We are also more acute in distinguishing
pitch for weaker sounds. Thus, bad music sounds best when played very
loud and screechy, where you can't perceive the pitch very well.
There is a point of diminishing returns, however. The sensitivity of the
ear to intensity is _not_ flat across frequency. For moderate (not soft)
levels in quiet, sine waves must be 20-30 dB more intense at 100 Hz than at
1 KHz to sound equally loud. Thus I copy CW with the RIT set to ~ -150 to
-250 Hz, which lowers the pitch to ~ 500 Hz and keep the intensity
moderate.
KIDS: Don't try this at home if you can't make a similar adjustment in
the receiver passband center, however.
Now if I could just fix my transmitted signal so _you_ all could hear me
clearly by just moving the XIT...
